ABSTRACT
Magnetic RAM (MRAM) is a new memory technology with access and cost characteristics comparable to those of conventional dynamic RAM (DRAM) and the non-volatility of magnetic media such as disk. That is MRAM retains its memory even after removing power from the device. Such a non-volatile memory has important military applications for missiles and satellites. Clearly such a device could also have important commercial applications if the non-volatility were accomplished without impacting other properties of the m ....etc

It is a step towards a new breed of computer chips that couple memory with information processing. Such chips retain data when computer is turned off, eliminating the time-consuming process of booting up information from hard drive to processor. If we can make semiconductor based magnetic memories when we turn on computer it would be like a TV set-all information will be there with no need for reloading the operating system. All spintronic computers eliminate the need for parallel processing. Computing could be accelerated and customized with r ....etc

INTRODUCTION
All materials have an inherent magnetic character arising from the movements of their electrons. Since dynamic electric fields induce a magnetic field, the orbit of electrons, which creates atomic current loops, results in magnetic fields. An external magnetic field will cause these atomic magnetic fields to align so that they oppose the external field. This is the only magnetic effect that arises from electron pairs. If a material exhibits only this effect in an applied field it is known as a diamagneti ....etc

The high-tech industry has spent decades creating computer systems with ever mounting degrees of complexity to solve a wide variety of business problems. Ironically, complexity itself has become part of the problem. As networks and distributed systems grow and change, they can become increasingly hampered by system deployment failures, hardware and software issues, not to mention human error. Such scenarios in turn require further human intervention to enhance the performance and capacity of IT components. This drives up the overa ....etc

1. INTRODUCTION

Impediments to main memory performance have traditionally been due to the divergence in processor versus memory speed and the pin bandwidth limitations of modern packaging technologies. End-user demands are forcing drastic changes in the applications, which use semiconductor memory products, and new applications are emerging with even more unique requirements. Some of these demands include a reduction in power, board space and cost, as well as increased density and performance. Flash memory has been the ans ....etc

INTRODUCTION

In 1984 Drs. Arthur Pohm and Jim Daughton, both employed at that time by Honeywell, conceived of a new class of magnetoresistance memory devices which offered promise for high density, random access, nonvolatile memory. In 1989 Dr. Daughton left Honeywell to form Nonvolatile Electronics, Inc. having entered into a license agreement allowing him to sublicense Honeywell MRAM technology for commercial applications. Dr. Pohm, Dr. Daughton, and others at NVE continued to improve basic MRAM techno ....etc
